Why does my IDI engine make a loud knock?

It’s not normal knock – it’s pretty damn loud. I do appreciate a normal cold IDI diesel engine is noisy but this is +30% extra.

What causes an exhaust manifold to crack on a Cummins 5.9L?

While the block will only expand by a fraction of an inch, the constant expansion and contraction causes a lot of stress on the exhaust manifold. As a result, the manifold (also made of cast iron) can crack. When the manifold cracks air leaks out, pressure is lost, and the engine loses vacuum.
